Thermostat schedule set, but doesn’t hold bottom heat temp

[InheritedNest]

I inherited my thermostat when I purchased my home.  The scheduled seemed to work very well for air conditioning, but now that it’s set on heat, it doesn’t hold my lower, overnight temp.  I have my schedule set at 65, but when I woke up this morning it was 52!  If I’m awake and in the house, I make sure to walk past the thermostat so it knows I’m home, or adjust it as needed, but I can’t do that while I’m asleep.  Any assistance would be greatly appreciated!

6.2-22 is the issue. I will continue to say it until Google pushes a fix. I have multiple nests. Both stopped working correctly when the last update came through. 

It is not my wiring. I've had these installed for years.
